Definitions

  • the invention relates to a new method for metering fine-particle solids by means of mechanical vibrations and devices for carrying out the method.
  • Solid materials have a rough surface. This requires high coefficients of friction, which are finely divided inorganic substances or micronized drugs (in which van der Waals forces also play a major role) make it difficult or impossible to escape from small openings (nozzles).
  • the metering of fine and ultra-fine solid substances is therefore often only possible if these substances are driven out of the storage container in connection with a carrier medium. In the case of the ceramic and jewelry industry, this is done by mixing the ceramic particles with water and applying them with a brush or by spraying on the suspension.
  • Micronized drugs are usually converted into aerosols with the help of propellant gases, for example for inhalation or nasal application.
  • the object of the invention is to propose a method and devices for its implementation, with which it is possible to dispense solid active substances / active substances of very small particle size in a dosage which can be changed if desired from a dosing device in certain amounts without using propellant gases or fluxing agents.
  • the object of the invention can be used wherever certain, in particular small amounts of fine powders are to be measured. Accordingly, suitable areas of application are, for example, the jewelry and ceramics industry and medical technology.
  • suitable areas of application are, for example, the jewelry and ceramics industry and medical technology.
  • the administration of medicinal products in powder form by inhalation and also nasal application plays an important role in this.
  • the device according to the invention essentially consists of a delivery nozzle (optionally connected to a storage container), coupled to a system that generates mechanical vibrations.
  • the coupling can take place indirectly or directly.
  • the nozzle (possibly with a storage container) is connected directly to a coil.
  • An intermittent current flowing through the coil causes the particles in the container to vibrate.
  • the vibration is so great that the particles only touch little or hardly.
  • the roughness of the surface is no longer a process-determining variable and van der Waals forces are also overcome. Due to the inherent movement of the parts, caused by the vibration, there is no longer any gate formation in front of the nozzle opening; ie the particles do not interfere with each other, but fall in the desired amount through the nozzle neck or nozzle opening.
  • the contact surface can be set exactly. If the frequency is far from the natural resonance of the particles, the particles will touch - the amount of particles falling through will decrease.
  • the flow rate can be precisely metered by changing the parameters frequency, amplitude and position.
  • the nozzle is glued to a membrane.
  • the membrane is coupled to a vibration generating system, e.g. consisting of a coil and an oscillator.
  • a vibration generating system e.g. consisting of a coil and an oscillator.
  • the oscillator frequency can be changed by means of the resonant circuit parameters (resistance, inductance, capacitance), the amplitude can be changed by regulating / controlling the gain. Tests with finished samples in the laboratory have confirmed the exact meterability.
  • the application rate can be changed in accordance with the process requirements. So the outflowing amount of active substances in medical processes can Inhalation flow of the patient can be adjusted.
  • the fill level of the dosing system is continuously detected and regulated within predetermined tolerance limits. This can e.g. by using optoelectronic sensors or by using weight sensors.
  • the vibrations are not applied electromagnetically in the form of a coil with an armature, but rather by an electric motor.
  • the dosing system is coupled to an electric motor with an imbalance. The change in frequency and amplitude are caused by changing the speed of the motor and changing its unbalance.
  • the vibration is applied by mechanical assemblies, e.g. a spring motor with unbalance.
  • mechanical assemblies e.g. a spring motor with unbalance.
  • the vibration is applied by using pneumatics and / or fluidics.
  • the vibrations are applied by vibration generators based on the piezo effect or, alternatively, by ultrasonic vibration generators.
  • the vibration generating systems are installed directly in the storage tank. Excitation can take place from the outside by means of electromagnetic fields or by direct energy supply to the storage container, coupled with the nozzle.
  • a locking mechanism is essential. This can be done e.g. in the form of a slide or in the form of a changing nozzle opening. For example, one embodiment provides for making the nozzle opening elastic. It can therefore be easily changed with the aid of purely mechanical as well as electrical or electromagnetic actuators.
  • the nozzle opening is coupled to a measuring device.
  • the measuring device designs the dosage of the smallest absolute amounts. Exact dosages of active ingredients are essential in medical technology.
  • the withdrawal process can be carried out in steps 1. Dosage, 2. Withdrawal.
  • two measuring devices in the form of half-shells or drilled holes provided with a collecting device. The half shells are pivoted. This means that one half-shell can always be filled and the material / active ingredient can be removed from the other.
  • the metering system is part of a handling device. It is envisaged that in the ceramic industry application, a robot will take the individual dosing systems with their own colors from a device, guide them to the workpiece, give an enable signal to the control / regulating circuit of the dosing system, and apply the ceramic particles together with the movement of the robot arm , and the dosing system is put down again. In this position, it is automatically refilled from a storage container by an upper closing mechanism.
  • the dosing system be so compact that it is built up in the order of a small spray can.
  • the output, in particular of extremely finely divided powders can be improved by adding coarser particles (size> 10 ⁇ m) or much smaller particles (size ⁇ 1 ⁇ m) of the drug or a physiologically acceptable excipient.
  • coarser particles size> 10 ⁇ m
  • much smaller particles size ⁇ 1 ⁇ m
  • Influence of moisture on the contents of the nozzle or the storage container can interfere.
  • a space separated by a suitable membrane such as Goretex®, which holds a drying agent such as silica gel.
  • a one-way valve can be switched on between the nozzle and the mouthpiece through which the patient inhales. This can prevent the humid air from reaching or entering the nozzle during exhalation.
  • Figure 1 shows a metering system according to the invention as a single assembly.
  • the nozzle 2 attached to its storage container 1 can be opened or closed by an electromagnetically operated slide 3.
  • the oscillation-generating system of coils comprises the secondary winding 4 and the primary winding 5, which lie inside the holding device 6. If a current pulsating at a certain frequency flows through the coil 5, the system is set in vibration. The particles 7 separate from each other and fall through the nozzle opening.
  • the dosing system is connected to a larger storage container by means of a flexible hose 8. Access to this storage container is controlled by a make / break contact 9.
  • the make / break contact is in turn coupled to level sensors 10 and 11.
  • the sensor 10 measures the maximum, the sensor 11 the minimum level.
  • the vibration-generating systems can be integrated in the storage container.
  • the material is simply mixed with particles that can be set in motion by electromagnetic fields, e.g. small rusty iron particles. However, these particles must be dimensioned so that they cannot fall through the nozzle opening.
  • Figure 2 shows the exact metering of the discharge amount with the aid of a measuring device.
  • the nozzle is represented by 12.
  • the measuring device is designed in the form of a rotating circular disk 13 with depressions 14. In the exemplary embodiment shown, the depressions are simply drilled holes. A solid plate 15 is located below the holes in the nozzle area.
  • the sequence is as follows: In the first step, the measuring device 14 is filled. Then the circular disk is rotated further and the particles fall down through the measuring device. At the same time, the second measuring device is filled again, so that the measured amount of material / active ingredient falls out with each cycle.
  • Figure 3 shows a compact simple embodiment of the invention. It consists essentially of a small loudspeaker with the magnet 16, the coil 17 and the membrane 18 to which the plastic pin 19 is glued. It transfers the vibrations of the loudspeaker to the content of the glass nozzle 21 provided with a plastic sleeve 20, which contains powder to be applied.
  • the opening 22 is expediently provided with a closure known per se.
  • the loudspeaker used here is one of the dynamic loudspeakers.
  • the coil is held free-swinging in the ring-shaped air gap of the permanent magnet by the membrane.
  • the nozzle is attached to the membrane so that the vibrations are transmitted to the nozzle which vibrates in the axial direction.
  • a suitable setting of the square-wave generator generates such a frequency that leads to resonance in the powder.
  • the nozzle opening can be very small (less than 1 mm in diameter).
  • FIG. 4 shows an embodiment of the nozzle 21 through which the narrowest point has the smallest possible axial extent, which is achieved by an opening 22 which is flared outwards.
  • FIG. 5 shows schematically how a device according to the invention (essentially corresponding to FIG. 1) can be integrated into a device for inhaling powdered medicinal substances.
  • the storage vessel 1 is provided with a nozzle 2 which can be opened or closed by the slide 3.
  • the coils 4, 5 with the holder 6 are used to generate vibrations.
  • the device is equipped with a refill device 23, a fold-out mouthpiece 24 with the switch-on contact 25 and a viewing window 26 for the optical fill level control Mistake.
  • a vacuum sensor and electronics 28 are provided as further components, the latter taking over vibration generation and control of the individual operations.
  • the switch 25 is actuated, whereby the electronics are armed for a certain period of time.
  • the vacuum sensor 27 detects the start of inhalation and then triggers the opening of the slide 3.
  • the electronics 28 now generate vibrations through which a desired dose of the powder is applied.
  • the vacuum sensor then detects the end of inhalation and switches off the electronics.
  • a conical seal can be used for the nozzle, which is opened by electronic control for the duration of the vibration generation.
  • nozzles can also be provided or the nozzle opening can be designed in the form of a sieve.
